5 FAQs of Refractory 5ml 25ml 50ml 100ml 300ml al2o3 alumina ceramic melting crucible with cap lid

What is the maximum temperature the alumina ceramic melting crucible can withstand? The alumina ceramic melting crucible can withstand continuous temperatures up to 1700°C (3092°F) and short-term peaks up to 1800°C (3272°F). Its high-purity Al2O3 composition ensures structural stability and thermal shock resistance, making it ideal for melting metals, alloys, and high-temperature materials without cracking or degrading. Are these crucibles chemically resistant to acids and alkalis? Yes, alumina ceramic crucibles exhibit excellent resistance to most acids, alkalis, and corrosive substances at high temperatures. However, prolonged exposure to hydrofluoric acid (HF) or highly concentrated molten alkalis may cause gradual erosion. Always verify chemical compatibility with your specific materials before use. What is the purpose of the cap lid? The cap lid minimizes heat loss, prevents contamination from airborne particles, and contains spills during melting. It also ensures a stable thermal environment, improving melting efficiency. The lid is made of the same high-purity alumina ceramic, ensuring consistent thermal and chemical performance. How do I choose the right crucible size? Select a crucible size based on your sample volume. For example, a 5ml crucible suits tiny precious metal samples, while 300ml is ideal for larger batches. Always leave 10–20% headspace to prevent overflow. Match the size to your furnace dimensions and ensure even heat distribution for consistent results. How long do these crucibles last, and how should I maintain them? Lifespan depends on usage frequency, thermal cycling, and chemical exposure. With proper care, these crucibles last dozens of uses. Clean them after each use with non-abrasive tools, avoid rapid temperature changes, and inspect for cracks or erosion. Replace the crucible if you notice significant wear, thinning walls, or surface pitting to ensure safety and performance.
